Repair Disk Error during Mountain Lion Install 2010 Macbook Pro
Hello All,
Last night like many of you I downloaded Mountain Lion to update to the newest Apple OS. During the install procress I was told my Harddrive was corrupted and needed to be repaired. After running the Verify Disk utility the following errors came up
Checking Catalog file,
Incorrect number of thread records
Incorrect number of thread records
Checking catalog hierarcchy.
Invalid volume file count
Checking volume information.
The volume Macintosh HD was found corrupt and needs to be repaired.
Then I used the repair utlity on the same screen.
The message was that it had attempted to repair it three times and it could not do so.
During the repair the error message incorrect number of thread records appeared twice.
Afterwards it no longer showed that harddrive as mounted and I cannot boot back into it. When booting it gives me the option of the Install Boot, the Recovery Boot, or my Windows Partition boot.
Two Questions
Is there a way to boot back into the OS to recover my files, I have most backed up but would like to get a few more on my external HD?
My other question is how can I sucessfully repair the disk so that I can do the above question and also install mountain lion.
Thank you,
Andrew
